The purpose of this experiment was to study the effects that nitric oxide (NO) has on the oxygen consumption, heat generation, and cell ultrastructure of seedlings of wheat (Triticum aestivum). NO was the molecule for testing because it has been found to be actively involved in important plant roles such as tropisms, flowering, stomatal openings, xylem formation, stress response, and adaptation. Plants produce NO in their leaves and in their roots. The conductors of this experiment are asking the question: What are the effects that NO has on plants when it is generated from an exogenous source?
I think it is safe to say that plants aren’t going anywhere and since plants are so crucial to the survival of our existence is to be grown and harvested, it is important to understand the mechanisms that are necessary to help these crops flourish. This experiment studies a molecule that could have potential to producing better crops. Since nitric oxide is associated with important roles in plants, it is plausible to hypothesize that when a plant receives this molecule from an external source, it could be beneficial to the plant. This study was done on the roots of wheat plants so that if this molecule could increase the productivity of plants, it could somehow be made into a fertilizer.
The authors of this experiment utilized the roots of 5 day old seedlings for this experiment. There were controls and experimental treatments of NaCl; NaNO2, as the donor of nitric oxide; protonophore; inhibitors of mitochondrial oxidation rotenone and antimycin; succinic acid as an oxidation substrate; and ascorbic acid as an antioxidant. . After the various treatments were applied, the amounts of...
